SPOOL HOLDER Filed May 3, 1934 Patented May 14, 1935 UNITED STATESPATENT OFFKIE srooL HOLDER Alexander Kaplan, Cleveland, Ohio ApplicationMay a, 19s4,-seria1 No. 723,653 '3 Claims. '(01. 242- 139) Thisinvention relates to spool holders, and has for its main object toprovide a spool holder of simple and practical construction which willsupport a plurality of spools of thread and prevent theft thereof.Another. object of the invention is to provide a spool holder ofsaidcharacter in which the spools upon the stopping of the sewing machine asis the case when the spool is rotated by the unwinding of the thread. 7

With the above and other objects in view, the 20 invention will behereinafter fully described as illustrated in the accompanying drawing,and the novel features will be distinctly pointed out in the appendedclaims.

In the drawing, similar characters of reference are used to designatecorresponding parts.

Figure 1 is a front elevation of a spool holder constructed inaccordance with my invention, certain parts being broken away to bettershow the invention,

3 Fig. 2 is an end elevation,

Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 1,

Fig. 4 illustrates the means for locking the lock plate, and

Fig. 5 illustrates the spool weight.

Referring to the drawing, l represents a stand which is adapted to befixed to the top of a sewing machine, and having a socket 2 forreceiving the lower and round end 3 of an upright rectangular guide andsupporting bar 4. A thumb-screw 5 is provided for securing the guide bar4 in the stand. Fixed to the guide bar 4 near its lower end is base 6having a central depending boss 1. Cast in. the base 6 are a pluralityof upstanding pins, indicated by 8, for the purpose of supporting spoolsof thread designated by 9, which rest upon the top of said base. Thepins 8 are arranged in opposite pairs and forming rows at each side ofthe longitudinal center line of the base. Depending bosses III at theunderside of the base provide better support for the pins 8.

Slidably mounted upon the guide bar 4 above the base 6 is a lock-plate Hof the same size and shape as said base and having a central upuse toprevent falling of the unwound thread wardly extending boss 12, which isprovided with a rectangular opening l3 for receiving said guide bar. Thelock-plate H is provided with a pluralitylof openings l4 arranged on thesame centers asthe pins 8, so that said openings will be aboveand'opposite theupper ends of the spools of thread- The lock-plate I Iis limited in its downward movement by means of a stop pin [5 fixed inthe upright bar 4, which point is below the upper ends of the pins 8. Asuitable lock 16 is provided in the boss [2, which boss is enlarged atits forward side for accommodating the lock. Said lock is operated by akey entering vertically at 18 and actuating the lock-pin l9. which isadapted to enter a recess 20 of the guide bar 4 and thereby lock theplate II to said guide bar and prevent vertical sliding movement of saidplate on said bar. The plate ll may thereby be locked and unlocked onlyby an authorized person.

Resting upon the upper end of each of the spools of thread is a disc ofmetal 2|, which is cupped out at 22 for receiving the end of the spool 9and provided with a central opening 23 for the pin 8. The disc of metal,due to its weight, prevents rotation of the spool by the unwinding ofthe thread therefrom, and the thread will not fall therefrom uponstopping of the sewing machine. The disc 2! is larger in diameter thanthe opening Id of the lock-plate ll so as not to pass therethrough andthereby prevent the spool of thread being lifted from the pin 8, whensaid plate is locked in position. The peripheral edge 24 of the disc 2|serves as a guide for the thread unwinding from the spool and is roundedin its vertical plane for smoothness in drawing the .thread over saidedge.

Fixed to the top of the bar 4 is a thread guide consisting of alongitudinally extending bar 25 having a central boss 26, and carryingcross-arms 21 arranged in vertical alignment with the transverslyopposite pairs of pins 8. At the free ends of the cross-arms 21 arehooks 28 for guiding the thread, indicated by 29,'unwinding from thespools, which hooks are directly over the pins 8. A stop pin 30 is fixedin the guide bar 4 for limiting the upward movement of the lock-plateII, and a recess 3| is provided in said bar adapted to receive thelock-pin IQ for holding said plate in its up position and thereby permitremoval or replacement of the spools of thread upon the pins 8.

From the drawing and description, it is apparent that spools of threadarranged on end may be locked against theft; that the spools of threadmay be conveniently and quickly placed in the holder by an authorizedperson; that the base supporting the spools of thread may be easilyremoved from the stand for carrying to an authorized person; that thespools of thread will remain stationary while the thread is unwindingtherefrom around the edge 24 and over same and through the guide hooks28.

Having fully described my invention, what I claim is: I I

1. In a spool holder, the combination of a base, pins projecting fromthe base adapted to receive spools, a bar projecting from the base, aplate slidably mounted upon the bar, the plate having openings oppositesaid pins, means for limiting the movement of said plate upon said bar,from a position below the upper ends of said pins to a position forpermitting removal of the spools from said pins, a lock carried bysaidplate, the lock having a lock-pin, and the lock-pin being adapted tolock said plate to said bar in either of said positions v 2. In a spoolholder, the combination of a base, pins projecting from the base adaptedto receive spools, a bar projecting from the base, a plate slidablymounted upon the bar, the plate having openings opposite said pins, ametal disc adapted to rest upon the upper end of each spool, the metaldisc being larger than said openings of said plate, means for limitingthe movement of said plate upon said bar from a position below the upperends of said pins to a position for permitting removal of the spoolsfrom said pins, a lock carried by said plate, the lock having alock-pin, and said bar having recesses adapted to receive said lock-pinwhen said plate is in either of said positions.
